Caitlyn, who's begun releasing short excerpts of the work in recent weeks, drops off a galley copy to Kris in the sneak peek above, and upon reading it, Kris claims to her daughters that she's been totally vilified.

"I read it and basically the only nice thing she had to say was that I was great socially at a party one time," she says. "None of it makes sense. Everything she says is all made up. Why does everything have to be that Kris is such a bitch and an a--hole?"

The exes seem to get along swimmingly in a separate sneak peek, but the good vibes seem to dissipate pretty quickly.

And admissions about Kris are just a taste of what's to come from Secrets. Already, Caitlyn has come clean about gender confirmation surgery and how she expects her sex life to consequently change.

“Of the most important things in my life, sex is beyond the bottom; it has been that way for a long time,” she writes. “A future female companion? Yes, I do think about that. A future female sex companion? Not happening, at least for now, and perhaps not ever.”
